| Subject: i40e: Fix log TC creation failure when max num of queues is exceeded |
| |
| From: Jedrzej Jagielski <jedrzej.jagielski@intel.com> |
| |
| [ Upstream commit ea52faae1d17cd3048681d86d2e8641f44de484d ] |
| |
| Fix missing failed message if driver does not have enough queues to |
| complete TC command. Without this fix no message is displayed in dmesg. |
| |
| Fixes: a9ce82f744dc ("i40e: Enable 'channel' mode in mqprio for TC configs") |
